Abstract

Die Erfindung betrifft eine Folie (1a, 1b, 1c) mit einem Trägersubstrat (2) aus einem Kunststoffmaterial, wobei die Folie zumindest eine antimikrobielle und/oder antivirale Beschichtung (3) aufweist und das Trägersubstrat (2) aus zumindest einem Fluorpolymer hergestellt ist.The invention relates to a film (1a, 1b, 1c) with a carrier substrate (2) made from a plastic material, the film having at least one antimicrobial and/or antiviral coating (3) and the carrier substrate (2) being made from at least one fluoropolymer.

Description

Die Erfindung betrifft eine Folie mit einem Trägersubstrat aus einem Kunststoffmaterial.The invention relates to a film with a carrier substrate made of a plastic material.

Darüber hinaus betrifft die Erfindung einen Verbundwerkstoff.In addition, the invention relates to a composite material.

Weiters hat die Erfindung ein Verfahren zur Herstellung einer Folie zum Gegenstand.The invention also relates to a method for producing a film.

Üblicherweise müssen Oberflächen mit Desinfektionsmittel gereinigt werden, um diese von Viren, Pilzen und Bakterien zu befreien. Nachteilig hierbei ist es, dass Viren, Pilze und Bakterien mit der Zeit Resistenzen gegen Desinfektionsmittel bilden können. Darüber hinaus ist eine regelmäßige Desinfektion der Oberflächen erforderlich, um Neuansiedlungen von Viren, Bakterien und Pilzen zu verhindern.Surfaces usually have to be cleaned with disinfectants to free them from viruses, fungi and bacteria. The disadvantage here is that viruses, fungi and bacteria can develop resistance to disinfectants over time. In addition, regular disinfection of surfaces is required to prevent reintroduction of viruses, bacteria and fungi.

Bei Gebäuden und Fahrzeugen, insbesondere in Innenbereich davon, sind auch die Brandschutzeigenschaften der verwendeten Materialien zu beachten.The fire protection properties of the materials used must also be taken into account in buildings and vehicles, especially in the interior of them.

Es ist daher eine Aufgabe der Erfindung, die oben genannten Nachteile des Stands der Technik zu überwinden und einen auch innenraumtauglichen Schutz von Oberflächen vor Viren, Bakterien und Pilzen zu schaffen.It is therefore an object of the invention to overcome the above-mentioned disadvantages of the prior art and to provide protection of surfaces against viruses, bacteria and fungi that is also suitable for indoor use.

Diese Aufgabe wird mit einer Folie der eingangs genannten Art erfindungsgemäß dadurch gelöst, dass die Folie zumindest eine antimikrobielle und/oder antivirale Beschichtung aufweist und das Trägersubstrat aus zumindest einem Fluorpolymer hergestellt ist.This object is achieved according to the invention with a film of the type mentioned at the outset in that the film has at least one antimicrobial and/or antiviral coating and the carrier substrate is made of at least one fluoropolymer.

Aufgrund der brandhemmenden Eigenschaften sowie der hohen mechanischen Belastbarkeit und Widerstandsfähigkeit gegenüber Chemikalien von Fluorpolymeren ermöglicht die erfindungsgemäße Lösung die Realisierung eines sehr effektiven antimikrobiellen und/oder antiviralen Schutzes von Gebäuden und Fahrzeugen. Die Erfindungsgemäße Lösung kann beispielsweise für die Realisierung von Trennwänden, Ausstattungen von öffentlichen Gebäuden, wie Flughäfen, Krankenhäuser, etc. Durch die antimikrobielle und/oder antivirale Beschichtung kann auf eine aufwendige chemische Desinfektion verzichtet werden. Zudem wird aufgrund des geringen Gewichtes die Verwendung der erfindungsgemäßen Folie für die Herstellung leichter und funktioneller Konstruktionen ermöglicht.Due to the fire-retardant properties and the high mechanical strength and resistance to chemicals of fluoropolymers, the solution according to the invention enables very effective antimicrobial and/or antiviral protection of buildings and vehicles to be implemented. The solution according to the invention can be used, for example, for the realization of partition walls, equipment for public buildings such as airports, hospitals, etc. The antimicrobial and/or antiviral coating means that complex chemical disinfection can be dispensed with. In addition, due to the low weight, the use of the film according to the invention for the production of light and functional constructions is made possible.

Als besonders vorteilhaft hinsichtlich der mechanischen und brandhemmenden Eigenschaften sowie der chemischen Beständigkeit hat sich eine Variante der Erfindung bewährt, bei welcher Ethylen-Tetrafluorethylen-Copolymere (ETFE), Polyvinylidenfluoride (PVDF), Perfluoralkoxy-Polymere (PFA), Tetrafluorethylen-Hexafluorpropylen-Copolymere (FEP).A variant of the invention that has proven to be particularly advantageous in terms of mechanical and fire-retardant properties as well as chemical resistance, in which ethylene-tetrafluoroethylene copolymers (ETFE), polyvinylidene fluoride (PVDF), perfluoroalkoxy polymers (PFA), tetrafluoroethylene-hexafluoropropylene copolymers ( FEP).

An dieser Stelle sei darauf hingewiesen, dass zwischen dem Trägersubstrat und der Beschichtung noch weitere Schichten, insbesondere Folien und/oder Haftvermittlerschichten, angeordnet sei können. Allerdings kann die Beschichtung auch direkt auf das Trägersubstrat aufgebracht sein.At this point it should be pointed out that further layers, in particular foils and/or adhesion promoter layers, can be arranged between the carrier substrate and the coating. However, the coating can also be applied directly to the carrier substrate.

Weiters sei angemerkt, dass in dem vorliegenden Zusammenhang der Begriff "antimikrobiell" im Sinne von antiviral, antibakteriell und fungizid verstanden wird, wobei es ausreicht, wenn nur eine dieser Eigenschaften verwirklicht ist.Furthermore, it should be noted that in the present context the term "antimicrobial" is understood in the sense of antiviral, antibacterial and fungicidal, it being sufficient if only one of these properties is realized.

Zur Erzielung der antiviralen und antibakteriellen Eigenschaften, kann die antimikrobielle und/oder antivirale Beschichtung antimikrobielle und/oder antivirale Additive aufweisen.To achieve the antiviral and antibacterial properties, the antimicrobial and/or antiviral coating can have antimicrobial and/or antiviral additives.

Als besonders vorteilhaft hat sich herausgestellt, dass die antimikrobiellen und/oder antiviralen Additive organische Biozide und/oder Metalle, Halbmetalle, Metall- oder Halbmetallverbindungen umfassen, wie beispielsweise Silber Ionen, Silberverbindungen, Wolframoxide, Molybdänoyid, Zinkmolybdänoxide, Kupfer, Kupferverbindungen, Titandioxid, Aluminium, Gold, Goldverbindungen, Platin, Platinverbindungen, Iridium, Iridiumverbindungen, Zinn, Zinnverbindungen, Antimon, Antimonverbindungen.It has been found to be particularly advantageous for the antimicrobial and/or antiviral additives to comprise organic biocides and/or metals, semimetals, metal or semimetal compounds, such as silver ions, silver compounds, tungsten oxides, molybdenum oxide, zinc molybdenum oxides, copper, copper compounds, titanium dioxide, aluminum , Gold, gold compounds, platinum, platinum compounds, iridium, iridium compounds, tin, tin compounds, antimony, antimony compounds.

Bei der bevorzugten Ausführungsform sind die Partikel so homogen in dem gesamten Volumen der Matrix bzw. der Beschichtung verteilt, dass in jeder erdenklichen Schnittebene durch die Beschichtung parallel zum Trägersubstrat antiviral aktive Partikel vorhanden sind. Dadurch sind Abnutzungs-, Abtragungs- bzw. Abrieberscheinungen unproblematisch hinsichtlich der antiviralen Eigenschaften der Folie. Solche Abnutzungserscheinungen (Abtragung von sehr dünnen Schichten) können z.B. durch Umwelteinflüsse wie Temperatur, Feuchtigkeit bzw. Sonneneinstrahlung und/oder. durch Reinigungsvorgänge oder dergleichen entstehen.In the preferred embodiment, the particles are distributed so homogeneously in the entire volume of the matrix or the coating that antivirally active particles are present in every conceivable section plane through the coating parallel to the carrier substrate. As a result, signs of wear, abrasion or abrasion are unproblematic with regard to the antiviral properties of the film. Such wear and tear (removal of very thin layers) can e.g. be caused by environmental influences such as temperature, humidity or solar radiation and/or. caused by cleaning processes or the like.

Um die Folie auf einen Gegenstand aufzubringen und diesen mit der Folie zu beschichten, kann es vorgesehenen sein, dass die Folie zumindest eine Klebeschicht aufweist, wobei das Trägersubstrat zwischen der Kleberschicht und der antimikrobiellen und/oder antiviralen Beschichtung angeordnet ist.In order to apply the film to an object and coat it with the film, it can be provided that the film has at least one adhesive layer, with the carrier substrate being arranged between the adhesive layer and the antimicrobial and/or antiviral coating.
